If you are there at 7pm or 8pm on the first day of the week, you might be lucky enough to find a raid group preparing to enter the Throne of Thunder. They might, in turn, be willing to join in while their team is getting ready.

It may have been fixed, but if you're an engineer you can make a macro that activates the lance and a Gnomish Cloaking Device at the same time and the boss despawns while the quest add spawns unaffected.

You actually don't even need a tank; you need someone to poke Nalak while you throw a spear at his ass and run the other way long enough for the add to run out of health. As for the redirect/despawn Nalak method, that's no longer working as of sometime during 5.3; I wound up eating a few deaths to help a friend get it done.

Hit up Open raid (http://www.openraid.us) as there's usually an Open Raid group of some sort that's active. Might be able to catch a Nalak group. Add the organizer to your battletag friends list then remove 'em once Nalak is dead.
